(c1. 24e- 15) l C L 'l Claims.

'his invention relates to resilient mountings for devices subject to vibration during operation and consists more particularly in a novel mount-4 ing for an electric fuel pump which is carried inside the fuel tank.

`My Patent 2,271,560 shows an effective antivibration mounting for this type of fuel pump. However, the assembling of the various mounting parts, after the pump is inserted into the tank, is rather diicult, especially since these operations must be performed by an operator reaching through a small hole in the tank wall.

It is an object of the present invention to pro.

vide an anti-vibration mounting for fuel pump, with means and attachment of cradle.

This object hereafter appearing are attained substantially by the structure illustrated in drawing in which:

Fig. 1 is a. diagrammatic view showing the pump installed in a fuel tank and connected to an internal combustion engine carburetor.

Fig. 2 is an enlarged top view of the pump and mounting structure.

Fig. 3 is a side view of on section line 3-3 of Fig. 2. l

Fig. 4 is a disassembled view oi a detail of the mounting structure.

Figs. 5 and 6 are detailviews showing .other means of mounting the rubber trunnions in the extremities of the yokes. I

Fig. 1 shows an Velectric fuel pump, generally designated at l0, supported within fuel tank II upon a mounting cradle, generally designated at I2, and connected to carburetor I3 by tubing I4. An electrical connection to storage battery I5 is made by means of vcable IB and wire I'I, both the pump motor and battery being grounded for completing the circuit. A plate I8 covers opening I3 in the top of the tank through which the fuel pump is inserted.

The, pump body has formed integral therewith four externally opening cups 22, each of which receives a rubber trunnion this type of to facilitate application the pump to its mounting and other more detailed objectsv the accompanying the same taken in part 23. A pair of iiarlgeclA pairs of cups the trunnions yoke extremities.

The mounting cradle is secured, as by welding, to the bottom of the tank and includes upright corner posts 30. Each post 30 has an inwardly projecting lug 3|` semicircular recess 32 for stably receiving the cylindrical under surface of one of the apertured yoke extremities (see Fig. 4). Each pair of posts 3U is connected'by an outward, horizontal flange 33.

The yokes are flanged as best shown irl-Fig. 3

and, in their vertical positions, indicated by broken lines in this figure, are conveniently positioned to form gripping handles to facilitate infsertion of the pump and mounting through opening I9. The vertical disposition of the yokes also reduces the lateral extent of .the pump and, consequently, the necessary size of `the tank opening.

After the pump is applied to the mounting cradle with all ofthe cylindrical extremities 25 firmly seated in recesses32, yokes 24 are swung outwardly so as to lie upon cradle anges 33.

The yokes and flanges are then secured togetherv by wing bolts 34 to maintain the assembly. Since only two of the wing bolts are required to secure the pump in position and these may be easily reached by the operator, the pump may be quickly and easily mounted. 24 rather `snugly follow the contour of cradle flanges 33 to provide additional stability.

In Fig. 45, rubber trunnion 23 is secured in yoke extremity 35 by a` screw Embedding of the screw against the trunnion causes the rubber to swell so as to tightly fill yokes 24, each has apertured, cylindrical extremities 25 receiving the projecting portions of a pair of these trunnons. Each extremity 25 has opposed, circumferential slots 26 extending partly therearound in which is inserted e, resilient, hairpin-like wire 21 which grips the enclosed rubber Aso that the assemblyof the yoke,` trunnion, and pump body is firmly maintained, while the yokes are permitted toswing about the axes of the the yoke eye. j

In Fig. 6, yoke eye 31 is provided with a small tongue 33. Trunnion 23 is distorted as indicated in broken lines for insertion into the yoke eye. The trunnion is made a little longer than` the space between the pump casingI and tongue 38 so that the trunnion is longitudinally compressed and thereby radially` swelled in the assembly to snugly fit the yoke eye.

The invention may be modified in details as will occur to those skilled in the art and the exclusive use of all modifications as come within the scope of the intended claims is contemplated.

I claim: g

1. Fuel pump mounting structure comprising spaced, resilient trunnions projecting from the pump body, a yoke having apertured extremities securely receiving said trunnions and maintain- 22. The wire clips 21 also cause to swell so as to firmly seat in the with an upwardly opening,l

The `edge flanges of yokes' 36 threadedinto the yoke.

" stably receiving said extremities, and securing means interposed between said extremities and engageable with said yoke'and cradle.

2. Fuel pump mounting structure comprising pairs of spaced trunnions projecting from the pump body, yokes each having apertured, cylindrical extremities receiving a pair of said trunnions, 'a cradle having recesses for stably positioning said extremities and having outwardlyvprojecting attaching surfaces, said yokes being swingable to positions aligned with the pump wall, to reduce the lateral extent thereof and thereby facilitate' application of the pump to said cradle, and said yokes also being swingable to outwardly projecting positions, and means for attaching said yokes to said surfaces.

3. Mounting structure as described in claim 2 and which said yokes have finger grip portions disposed, when said yoke is alignedwith the pump walls. to provide convenient hand gripping members to facilitate application to and removal from said cradle. y

4. In combination, a tank having an opening in a wall thereof, a fuel pump having a handle yoke with its extremities pivoted to the pump body and swingable to a position substantially aligned with the Wall Aof the pump body to'facilitate insertion and withdrawal through said openingza cradle mounted on another wall of said tank and having recessed structure for stably receiving and positioning said pump and having an outwardly projecting securing part, said yoke being swingable outwardly of the pump body, after insertion through said opening, and means for attaching said yoke to said securing part.

5. Mounting structure for a device subject to vibration in operation comprising recesses in spaced walls of the device, rubber trunnions rotatably seated in said recesses, a handle yoke having apertured extremities receiving said trunnions. said extremities having circumferential Slots, and sprlng'wires inserted in said slots and gripping said trunnions to secure the latter in pomtion.

6. Fuel pump mounting structure comprising a base for attachment to a tank inner wall and having outstanding spaced legs and flanges connecting pairs thereof, said legs having recesses, and handle yokes each pivotally mounted on the pump body and having cylindrical extremitieseseated in said recesses and attaching means, said yokes being swingable into substantial alignment with the pump body wall, to facilitate handling, and to outward positions for attachment of said means to said base anges.

7. Mounting structure for a device subject to vibration in operation comprising spaced trunnion pockets in the wall of the device, a handle yoke having an eye adjacent to and axially aligned with each of said pockets, rubber truntaining the assembly of said trunnions with the device, a cradle, and means located intermediate said eyes for securing said yoke to said cradle.
